Disable ingestion in stress tests when PutEntity is used (#10769)

Summary:
`SstFileWriter` currently does not support the `PutEntity` API, so in `TestIngestExternalFile` all key-values are written using regular `Put`s. This violates the assumption that whether or not a key corresponds to a plain old key-value or a wide-column entity can be determined by solely looking at the "value base" used when generating the value. The patch fixes this issue by disabling ingestion when `PutEntity` is enabled in the stress tests.
